When the Department of Energy’s Advanced Research Projects Agency–Energy launched the Optimizing Nuclear Waste and Advanced Reactor Disposal Systems (ONWARDS) program in 2022, it posed a challenge that the nuclear industry had never seriously confronted before: how to design waste management solutions that anticipate the coming shift to advanced reactors and not merely retrofit existing systems built for an older generation of technology. The program’s objectives were ambitious—reduce disposal footprint, enable scalable pathways for unfamiliar waste streams, and build the technical foundations for future disposal—yet also tightly grounded in the realities of emerging nuclear fuel cycles. For the nuclear community, this was a timely call. Advanced reactors were accelerating toward deployment, but the waste management systems needed to support them had not kept pace.

Nuclear waste technology company Deep Isolation Nuclear has launched a multiyear demonstration program of its deep borehole technology for disposing of nuclear waste. The full-scale, at-depth deep borehole demonstration program is being done in collaboration with Halliburton, Amentum, NAC International, and Occlusion Nuclear Solutions, along with the Deep Borehole Demonstration Center (DBDC).

Nuclear waste disposal technology company Deep Isolation Nuclear has announced the completion of a three-year project to manufacture, physically test, and validate a disposal-ready universal canister system (UCS) for spent nuclear fuel and high-level radioactive waste from advanced reactors.

Deep Isolation announced that it hosted its third technical workshop for the UPWARDS project, a Department of Energy Advanced Research Projects Agency-Energy (ARPA-E) initiative aimed at developing a universal canister system (UCS) for the disposal of radioactive waste streams from advanced reactors. The workshop, held at R-V Industries in Honey Brook, Pa., focused on the large-scale manufacturing and commercialization of the UCS.
